class IGNSSSensor

File Information

Library: IoT/Devices
Package: Generated
Header: IoT/Devices/IGNSSSensor.h


The interface for GNSS/GPS receivers.

Implementations of this class should also support the following (optional) properties for configuration:

  • positionChangedPeriod (int): the minimum time interval in milliseconds between firings of the positionUpdate event.
  • positionChangedDelta (int): the minimum distance (in meters) the receiver must move before the positionUpdate event is fired again.
  • positionTimeout (int): Timeout in milliseconds after which the positionLost event is fired if no valid position has been received from the GNSS receiver.

Creates a IGNSSSensor.


~IGNSSSensor virtual

virtual ~IGNSSSensor();

Destroys the IGNSSSensor.

Member Functions

altitude virtual

virtual double altitude() const = 0;

Returns the current altitude above sea level in meters. Returns -9999 if no altitude is available.

course virtual

virtual double course() const = 0;

Returns the current course in degrees [0, 360).

hdop virtual

virtual double hdop() const = 0;

Returns the Horizontal Dilution Of Precision (HDOP) in meters, or -9999 if no HDOP value is available.

isA virtual

bool isA(
    const std::type_info & otherType
) const;

Returns true if the class is a subclass of the class given by otherType.

magneticVariation virtual

virtual double magneticVariation() const = 0;

Returns the current magnetic variation in degrees [0, 360). Returns -1 if no magnetic variation is available.

position virtual

virtual IoT::Devices::LatLon position() const = 0;

Returns the last obtained position.

If no position is available, latitude and longitude will both be 0. To disambiguate with a real position, also check positionAvailable().

positionAvailable virtual

virtual bool positionAvailable() const = 0;

Returns true if a valid position is available.

remoting__enableEvents virtual

virtual std::string remoting__enableEvents(
    Poco::RemotingNG::Listener::Ptr pListener,
    bool enable = bool (true)
) = 0;

Enable or disable delivery of remote events.

The given Listener instance must implement the Poco::RemotingNG::EventListener interface, otherwise this method will fail with a RemotingException.

This method is only used with Proxy objects; calling this method on a RemoteObject will do nothing.

remoting__typeId static

static const Poco::RemotingNG::Identifiable::TypeId & remoting__typeId();

Returns the TypeId of the class.

speed virtual

virtual double speed() const = 0;

Returns the current speed in nautical knots. If no speed is available, returns -1.

type virtual

const std::type_info & type() const;

Returns the type information for the object's class.
